Tallahassee Yard Drainage Yard Regrading in Tallahassee, FL

The first ten feet, and the rule most older lots miss

The standard is a fall of five percent across the first ten feet out from the foundation, which works out to roughly six inches of drop. It is not a suggestion from a landscaper, it is the grading standard residential construction is held to, and a great many Tallahassee houses built before it was consistently enforced fall short of it somewhere around the perimeter.

Shortfalls are rarely uniform. A house can have textbook fall along three sides and a flat or reversed section behind an addition, under a deck, or where a bed was built up against the wall over the years. That one section is where the water sits, and finding it takes a level rather than an opinion.

Fill that stays where it is put

Soil brought in to correct a grade gets placed and compacted in layers, generally six to eight inches at a time, rather than dumped to final height in one go. Uncompacted fill looks correct on the day and resettles into the same depression within a season or two, which is why a regrade that was done cheaply tends to need doing twice.

Clay complicates this. It holds moisture, and compacting it wet produces a dense layer that sheds water rather than letting any of it through, which can be exactly what is wanted next to a foundation and exactly what is not wanted in the middle of a lawn. Where the fill goes and what it is made of are separate decisions.

When moving dirt will not be enough

If a test hole fills and then drains slowly, the lot has a percolation problem rather than a slope problem, and no amount of reshaping the surface will change what happens below it. Regrading still helps, because getting surface water moving reduces the load, but the water that has already soaked in still needs a route out.

The combination that solves most persistent Tallahassee wet spots is correcting the grade so surface water leaves, and adding a drain so subsurface water has somewhere to go. Doing only the first is the most common reason a homeowner is on their second contractor.

What happens to the lawn and the planting

Sod in the affected area comes up and goes back down, and it knits back in given water. Established beds get worked around where the grade allows it. The one thing flagged before work rather than after is mature trees, because adding depth of fill over a root zone can kill a tree slowly enough that nobody connects the two events.

What it costs, and what moves the number

The variables that actually drive the price of a regrade are the area being reshaped, how much fill has to be imported, and access. Access is the one people underestimate: a back yard reachable only through a narrow side gate means soil moved by wheelbarrow rather than by machine, and that changes the labour figure far more than the extra few yards of dirt does.

The other swing factor is what happens to the spoil. Cutting a high area produces soil that has to go somewhere, and if there is a legitimate use for it elsewhere on the property that is a saving. Spreading it into the low spot that was the original problem is not a legitimate use, though it is a tempting one, and it is worth asking directly where excavated material is going.
